Blue dots represent the patients in the lowest tTSSTRE group (values < 5000 (SUV x mL), n = 106). Green dots represent the patients in the medium tTSSTRE group (values 5000–15,000 (SUV x mL), n = 56). Brown dots represent the patients in the largest tTSSTRE group (values > 15,000 (SUV x mL), n = 41). The blue, green and red lines represent the fitted line for the peptide values of each tTSSTRE group. a Regression analyses whereby the mean tumor absorbed dose is plotted against the administered amount of peptide at the first PRRT cycle in respect to the patient`s total tumor somatostatin receptor expression (tTSSTRE). b Correlation between amount of administered peptide and the tumor-to-kidney absorbed dose ratio, with respect to the total tumor somatostatin receptor expression (tTSSTRE). c Correlation between amount of administered peptide (µg) and the tumor-to-liver absorbed dose ratio, with respect to the total tumor somatostatin receptor expression (tTSSTRE). d Correlation between amount of administered peptide (µg) and the tumor-to-spleen absorbed dose ratio, with respect to the total tumor somatostatin receptor expression (tTSSTRE). e Correlation between amount of administered peptide and the mean kidney absorbed dose with respect to the total tumor somatostatin receptor expression (tTSSTRE)
